Since there isn't a logical XOR operator in C, you could do this: if (!!ret->source.adapter.data.fchost.parent_wwnn ^ !!ret->source.adapter.data.fchost.parent_wwpn) > + virReportError(VIR_ERR_XML_ERROR, "%s", > + _("must supply both parent_wwnn and " > + "parent_wwpn not just one or the other")); > + goto error; > + } > + Is there any other identifiable info available at this point that could give more useful context to the log message? If nothing else, maybe log whichever of the two values is set so there would be something for the user to search on when looking for the offending xml. (I see the error log in commit 2b13361bc has the same problem). > } else if (ret->source.adapter.type == > VIR_STORAGE_POOL_SOURCE_ADAPTER_TYPE_SCSI_HOST) { > if (!ret->source.adapter.data.scsi_host.name && ACK, but I'd prefer if the error log gave more identifiable information. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
